I have a server 2012 WDS currently working with no issues re-imaging a range of HP laptops 9480m9470M6570b6560b

We are getting a new model of laptop we are doing some testing its a HP 840 G3 when we PXE boot it loads the boot image I select it but then I get an error msg

WdsClient: An error occurred while obtaining an IP address from the DHCP server.Please check to ensure that there is and operational DHCP server on this network segment.﻿

﻿﻿I've loaded the relevant NIC drivers in the boot.wmi and also the driver group but I still get the same error message. laptop is on the latest BIOS and we have tried imaging using a win 10 and win 7.

When I hit (shift+﻿f10) i do ipconfig /all and it indicates that I have no NIC adapter and i have also tried loading it using drvstore cmd and it still failed.
